The first of a trilogy, the far-future plot of this audiobook concerns various factions battling to help or prevent a religious movement from undertaking a pilgrimage to a world hidden within a mysterious void, a journey with the potential to significantly advance the human race—or destroy the galaxy. Listeners to Hamilton's complex SF epic must devote a fairly significant amount of time, patience and attention to the task. A single chapter lasts for hours; within each chapter, the perspective and story line shift multiple times, with no audibly perceptible break. It's comparable to being lost in a strange, dark and, above all, vast room, and takes a while to adjust. Gradually, though, plot lines begin to take shape, and the compelling story and relentless pace drives listeners forward through a highly enjoyable trip. John Lee enunciates a daunting amount of exposition with precision and provides his share of creditable accents and voice pitches. A Del Rey hardcover (Reviews, Feb. 4). (July)
